Re: MTRX Studio distortion on outputs
Quote:
You might want to try to contact Digital Audio of Denmark tech support (the makers of the MTRX and MTRX Studio) and find out. It’s a bit surprising to me that if this is a problem, they haven’t documented it already in the install manual. But I would experiment with disconnecting either the ground, or the - signal. Traditionally with a transformer output (which the MTRX is not) you would connect: Balanced XLR + (pin 2) = + (Tip) - (pin 3) = GND (Sleeve) GND (pin 1) = GND (Sleeve) For electronically balanced outputs, the configuration would be either: + (pin 2) = + (Tip) - (pin 3) = GND (Sleeve) GND (pin 1) = not connected Or + (pin 2) = + (Tip) - (pin 3) = not connected GND (pin 1) = GND (Sleeve) The last setup was what was recommended for the 192 I/O. One of the above setups should work, and will be clean and without distortion. The other one will probably not work, be filled with hum or just not pass signal at all. So you’ll just have to try both. You could get balancing transformers, but that would add coloration and expense. |

Re: MTRX Studio distortion on outputs
The output of the MTRX/MTRX Studio should always be connected to an unbalanced input like this:
+ = + GND = GND - = do not connect Do note that this will result in unbalanced operation and the output level will therefore be 6 dB lower when compared to balanced operation.

I wrote an email and they said i had to turn to AVID or my reseller. Non of them responded. Avid i had to pay, ofc. But I would experiment with disconnecting either the ground, or the - signal. Thanks Tone_Meachanic. It turns out you got it right! |

Now i have confirmation about this. A 6dB loss is no problem. Without the described connection i had a 18dB loss. Just to get the picture: is the signal still good if i did remain below the +6dB of output trim when if connected - to GND? Or is the signal already compromised below that output level in that order?

Re: MTRX Studio distortion on outputs
Signal is only good if you connect as I have described.
